- Make sure that you have followed Get started with connectors.
- Alacriti access: An active account in the Alacriti environment.
- Network connectivity: Confirmed routing between the Alacriti environment and the Grand Central (GC) iPaaS.
- Environment details: The following environment variables are needed from Alacriti to configure the connector:
| Environmental Key | Description |
|---|---|
alacriti-url | The base URL to access the Alacriti environment |
alacriti-client-key | The unique identifier assigned to the client by Alacriti |
Configuration guide
Follow these steps to initialize and authorize your Alacriti connector.1. Establishing connectivity
Share the following details with Grand Central team to establish secure connectivity between Grand Central and Alacriti-
Environment details:
baseUrlandipaddressof Alacriti application.Istio configuration: To add Alacriti IPs and DNS to the allowlist, see this page which describes how to configure Istio and how to add IPs and certificates to the allowlist.
2. Environment configuration
To initialize the Alacriti connector, you must define specific environment variables within yourgc-applications-live repository.
These variables are stored in the payments-v0.values.yaml file and handle outbound request and inbound-payments-v0.values.yamlinbound webhook events.
Define outbound parameters
These variables authorize and route requests sent from Grand Central to Alacriti.| payments-v0.values.yaml | Description | Environmental Key |
|---|---|---|
alacriti.baseUrl | Target API endpoint for the Alacriti gateway. | alacriti-url |
alacriti.client_key | Unique organizational identifier assigned by Alacriti. | alacriti-client-key |
alacriti.client_requestor_reference | Mandatory: Internal identifier for audit logging. | |
alacriti.product | Products to indicate what type of transfers are supported (eg: business_transfer) | |
alacriti.payment_channel | Payment channel to identify its business banking or retail baning or any other channel (eg: business_banking) | |
alacriti.requestor_type | Who is requesting the payment as its a party or company or any mode (eg: party) | |
alacriti.access_channel | If mutiple organisation or banks inside main organisation we can split it into various access channel (eg: backbase_business) | |
retryFlag | Set to true to enable automatic request retries. |
payments-v0.values.yaml:
Define inbound/webhook parameters
Configure how Grand Central receives asynchronous updates from Alacriti to GC.Set up the sync-hub component as described in Sync Hub. The following ASB variables are available after configuring Sync Hub. This is a mandatory component for inbound connectivity.
Webhook registration: To process asynchronous updates (for example, successful settlements or network rejections), you must share the Grand Central webhook url with Alacriti which needs to be registered.
| inbound-payments-v0.values.yaml | Description |
|---|---|
asb.event.version | Version of the Async Service Bridge (ASB) schema. |
asb.producer.apiUri | The callback URI for receiving incoming events. |
asb.event.topic | The ASB topic to send messages. |
asb.event.type | The ASB event type to send messages. |
asb.event.source | The ASB source to send messages. |
Below is a sample
inbound-payments-v0.values.yaml:
CustomLabels: CustomLabels are part of the Sync Hub setup. Once Sync Hub is enabled, adding the customLabels to the connector automatically invokes the Sync Hub URLs.
Testing your integration
To access the Payments Unified API, you must include your Grand Central subscription key in the request header. If you do not have a key, please contact the Grand Central Support Team to have one provisioned.| Key | Value |
|---|---|
api-key | <your_subscription_key> |
Webhook integration: Share the API Key through 1Password or any standard tool with Alacriti to call the inbound APIs.
Troubleshooting
If your connector isn’t responding as expected, check these common scenarios.5XX : Internal server error / Core system is down
5XX : Internal server error / Core system is down
Cause: The Grand Central (GC) gateway cannot establish a handshake with the Alacriti endpoint. This typically indicates an upstream service outage at Alacriti or a network routing failure.Solution: Verify the operational status of the Alacriti environment with Alacriti. If the service is operational, contact the GC Support team.
5XX : Timeout from Core / Read timeout / SocketTimeoutException
5XX : Timeout from Core / Read timeout / SocketTimeoutException
Cause: The Grand Central (GC) gateway cannot establish a handshake with the Alacriti endpoint. This typically indicates an upstream service outage at Alacriti or a network routing failure.Solution: Verify the operational status of the Alacriti environment with Alacriti. If the service is operational, contact the GC Support team.
Invalid OAuth Token
Invalid OAuth Token
Cause: The
client_id or client_secret provided during setup is incorrect.Solution: Re-verify your credentials with the Alacriti portal and contact the GC team to update the connection.429 : Rate limit Exceeded
429 : Rate limit Exceeded
Cause: The number of incoming requests has exceeded the defined threshold for your subscription tier. This “429 Too Many Requests” response is a protective measure to ensure the stability of the Grand Central and Core Banking infrastructure.Solution: Review your application’s request patterns to identify unexpected spikes. If your business requirements have evolved and you require a higher throughput, contact the Grand Central Team to request an adjustment to your APIM rate limit policy.
